SWING.

Application nled November 12, 1921.

To (1.7K whom. it may concern:

:86 it known that we, Gjuoncn MANIKOWSKE and lVARnnN J. 'GAnLsoN,citizens of the United States, residing at Minneapolis, in the county ofHenncpin and State of Minnesota, have invented certain new and usefulImprovements in Swings; and they do hereby declare the following tobe afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

Our invention relates to improvements in swings of the type having meanswhereby the occupant may start and propel the same by foot and armmovements and is in the nature of an improvement on the Clipfell andManikowske U. S. Letters Patent 1,335,938, issued April 6th, 1920.

To the above end, generally stated, the invention consists of thenoveldevices and con'ibimxtions ct devices hereinafter described anddefined in the claims.

In the accompanying drawings, which illustrate the invention, likecharacters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a perspective view of the improved swing;

Fig. 2 is a view principally in vertical section taken on the line 22 ofFig. 1 on an enlarged scale; and

Fig. 3 is a detail view with some parts sectioned on the line 3-3 ofFig. 1.

The numeral 1 indicates an overhead swing support in the form of a beam,to which is rigidly secured, a pair of edgewise spaced, transverselyextended head plates or bars 5. To the ends of these plates 5 aresecured front and rear pairs of depending swing supporting hooks 6 and7, respectively. It is important to note that the forward ends of theplate 5 are downwardly offset to position the front pair of hooks 6 at alower elevation than the rear pair of hooks 7 The improved swingincludes a seat 8' rigidly secured to the lower ends of a pair ofsuspending rods 9, which in turn, are suspended by cables 10 from therear pair of hooks 7 The suspending rods 9, at their lower ends, extendthrough bores in the ends of the seat 8 and are rigidly secured theretoby opposing nuts 11 having screwthreaded engagement therewith.

Serial No. 514,814.

To brace thesuspending rods 9 and thereby hold the same against angularmove ment in respect to the seat 8, there are provided segmental bracebars, 12 which extend transversely over the seat 8, and have in theircrowns, bores 13 through which said rods extend. The braces 12 extendfrom the front to the rear edges of the seat 8 and their lower endportions are extended toward each other on the bottom of said seat andare rigidly secured thereto, by the suspending rods 9 and the nuts 11,and nut-equipped bolts 14:.

The upper ends of the suspending rods 9 are bent to form eyes 15, towhich the suspending cables 10 are attached, and then extended laterallytoward each other and connected by a coupling 16 to aiford a tierod 17.This tie-rod. 17 serves a double purpose, in that it holds thesuspending rods '9 in parallel arrangement and from being pulled apartat their upper ends,

either by accident or otherwise, and it also prevents the occupant ofthe swing from standing on the seat 8.

Sleeve-like handles 18 are slidably mounted for endwise movement on thesuspending rods 9 and have secured to each of their ends, by screwthreads, bearing heads 19.

These bearing heads 19 have sockets 20 in which are mounted bushings 21having direct engagement with the suspended rod 9, and hold the handles18 and bearing heads 19 out of engagement therewith. The bushings 21 arepreferably made from pieces of hardwood, which, previous to theirapplication to the bearing heads 19, have been boiled in parafline andwhich parafiine acts as a lubricant for the bushings on the sus pendingrods 9.

Formed'with the bearing heads 19, are cup-like guard flanges 22 whichprevent the occupant of the swing or a. person taking hold of thesuspending rods 9, while the swing is in motion. from being pinchedbetween the handles 18 and said rods. It is obvious that, when the swingmoves downwardly the handles also slide downwardly on the rods 9. If, atthis time, thehands of the swing-occupant happen to be grasping the rods9, below or above the handles, they are engaged by the the lower rim ofthe cups 22 and prevented from contact with that portion of the rodwhich passes through the bushing 21, and hence cannot become pinchedbetween the bushing and said rod.

The handles 18 are held suspended on the rods 9 by pulling members orcables 23, the upper ends of which are secured to the front pair ofhooks 6 and their lower ends are secured in eye-equipped lugs at on theupper pair of bearing heads 19.

A horizontal foot rest 25 extends in front of the seat 8, and below thesame, and is in the form of two endwise positioned rods, the outer endportions of which are extended laterally and upward, to afi'ord a pairor arms 26 attached to the lower pair of bearing: heads 19 by screwthreaded engagement.

v[is shown the two rods forming the foot rest 25 are connected by acoupling 27 having screw-threaded engagement therewith.

The suspending cables '10 and pulling cable 23 are releasably attachedto the hooks 6 and 7 by blocks 28, preferably of fiber, and have boresto receive said hooks and also have a plurality of bores through whichsaid cables are laced to adjustably connect the same thereto.

The purpose of attaching the pulling cables 23 at a lower elevation thanthe suspending cables 10, and the manner of setting up and maintainingmotion to the swing is fully set forth in the patent hereinbeforeidentified and for the purpose of this case it is not thought necessaryto again re eat the same.

' at we claim is:

1. A swing comprising a seat, suspending members attached to the seat,and sleeve-like handles slidable on said suspending members and havingflaring end portions of greater internal diameter than the intermediateportion of said handles, whereby to hold the hands of the swing occupantaway from the points of contact between the handles and the suspendingmembers, during the motions of the swing, substantially as described.

2. A swing comprising a seat, a pair of rods extending through bores insaid seat and rigidly secured thereto, arch-like braces extendingtransversely over the seat from the front edge to the rear edge thereofand having in their crowns bores through which said rods extend, the endportions of said braces being extended transversely under the seat andrigidly secured to the bottom thereof, and a pair of suspending cablesattached to the suspending rods.

In testimony whereof we afiix our signa- I tures.
